News question: Know your ProtoDUNE detectors?

Quiz time: This week we’re spotlighting news about dual-phase ProtoDUNE detectors.

But first, join Fermilab News at Work in congratulating Laura Haseltine for winning last week’s quiz. Strontium electrons are energized longer than rubidium electrons, which means they have an increased lifetime and are the better atomic clock for measuring the amount of time it takes laser light to repeatedly traverse the length of a vacuum tube. Thank you to everyone who participated.

Now, show off your knowledge of the news coming out of Fermilab in this week’s quiz. A winner will be randomly selected from all lab employees and users who submit the correct answer to today’s question by noon CT today, Oct. 10.

This week’s question: What type of interaction is the dual-phase detector technology expected to be more sensitive to, compared to the single-phase technology? (Hint: See “Tests start at CERN for large-scale prototype of new technology to detect neutrinos.”)

Good luck! We will announce the winner and answer next week.

Past winners are welcome to participate in the quiz each week. However, only one win per person will be recognized in any 30-day period. The winner is recognized in the following week’s quiz and rewarded with a small token.
